This study describes the progress that has been made using a dedicated split bore 1.0 Tesla magnet to provide an MRI-guided radiotherapy system. This magnet design has a number of advantages including patient entry in two orientations to investigate competing magnetic field-beam configurations. A number of beam and imaging experiments, including first in vivo results, are described which show the efficacy of the system as an integrated inline MRI-Linac.
